By popular demand, here is another partner review. This time on solving quadratic equations by either square root or by factoring and Zero Product Property. I always use this as an in-class practice the day before moving on to completing the square. So this partner review does not have students using the completing the square strategy or the quadratic formula.
If you have never tried one of my partner reviews, this is how it works: Partners work side by side with different, but similar worksheets. Partner A has all of Partner B's answers on the back of his or her worksheet. Partner B has all of Partner A's answers on the back of his or her worksheet. Partners work one problem at a time on their own worksheet, then check each other's answers. Students are warned...help, but don't cheat.
We all know that mixed practice is so important, especially with quadratics. But how can you help 36 students or more at once? This activity allows students to help one another with confidence. Low students can even help high students because they have the worked out answers to their neighbor's paper. Two low students can study and try to understand the answer together.
The problem types included on this review are:
Solving quadratics with no b-term by square root to perfect square answers.
Solving quadratics with no b-term by square root to simplified radical answers.
Solving simple trinomials by factoring and zero product property (shows the "magic x" strategy.
Solving trinomials where a is not 1 by "magic x" strategy and grouping, and then by zero product property.
Solving binomials with a b-term by factoring out x and zero product property.
Some of the problems have the trinomial set = to zero to start. Some of them have the constant on the right, and need the addition property of equality applied first to bring the trinomial together.
The very last problem has a common factor that will factor out leaving a simple trinomial (if students catch it).
Try this once and you will be hooked. Give a good speech about expected behaviors and you will hear more peer tutoring going on in your room than ever before. This frees you up to facilitate rather than having to tutor everyone at once.
I have scanned in all the worked out answers so you can just print. ***Remember....print partner A's answers on the back of B's work, and print partner B's answers on the back of A's work.***
This review would work well for any level of beginning Algebra, from middle school to college. I use it as an end of chapter practice or review, but it would work well at the end of the semester before midterms, and also before final exams. This is also a GREAT activity to leave when you must have a substitute.
